Laboratory apparatus fitted with wells and used for temperature-controlling specimens

Abstract

A laboratory temperature controlling apparatus including container-like wells ( 2 ) disposed in a unit in a plane. Heating devices and cooling devices drive the wells. The wells have thin walls, and the heating devices include electrically powered heating wires that are coiled around the exterior surface of the wells. The coiled heating wires generally match an external contour of the wells. The cooling device may be a blower disposed to blow air over the exterior surface of the wells.

1 . A laboratory temperature controlling apparatus comprising container-like wells ( 2 ) configured in a unit in a plane, further comprising heating and cooling means ( 5 ,  6 ) driving said wells, 
 characterized in that 
 the wells ( 2 ) exhibit thin walls and in that the heating means include electrically powered heating wires ( 4   a ,  4   b ) which are configured as coils ( 5 ) surrounding the wells ( 2 ).  
   
     
     
         2 . Apparatus as claimed in  claim 1 , characterized in that the coils ( 5 ) geometrically match the external contour of the wells ( 2 ).  
     
     
         3 . Apparatus as claimed in  claim 1 , comprising wells ( 2 ) configured in rows in said plane, characterized in that the coils ( 5 ) within said rows are electrically series-connected.  
     
     
         4 . Apparatus as claimed in  claim 1 , characterized in that the wells ( 2 ) are mechanically connected to each other in the zone of their aperture rims.  
     
     
         5 . Apparatus as claimed in  claim 4 , characterized in that the wells ( 2 ) are impressed into a closed plate ( 1 ).  
     
     
         6 . Apparatus as claimed in  claim 1 , characterized in that the cooling means is an air blower ( 6 ) blowing air onto the outside of the wells ( 2 ).
